The Boardwalk officially opened on May 15, 1923, and has welcomed generations of thrill-seekers and sunbathers to the area known as the people's playground.

"Many people were shocked to learn that the Boardwalk was not a landmark already. This is an internationally recognized iconic structure," said City Councilman Mark Treyger (D-Brooklyn), who pushed the designation.

The landmarking means the structure of the Boardwalk cannot be removed.
